Hello everyone, I really fancy playing through Mystical Ninja again on the N64, but unfortunately it's one of the '64 games that requires use of a "Controller Pak" to save. Now, even during the N64's lifetime, third-party memory packs were utterly unreliable. I've got hold of an official Nintendo Controller Pak (second-hand) but it's just as useless, with the saves rarely lasting longer than 24 hours - I think it's an age thing. I doubt very much I could get hold of anything not second-hand in terms of N64 accessories nowadays. I know I could play the game via emulator but it just isn't the same. Anyone got any suggestions?

Sounds like it might just be the battery in the controller Pak that needs changing. Unfortunately the official Nintendo ones had the batteries soldered in rather than just held in by tabs like most of the third party ones, so it could be difficult to replace.

I believe the battery is just to actually retain the save data once it's disconnected from the mains power provided by the powered on console.

Of course it could also be something entirely besides the battery, but that just seems like the most obvious reason from a brief look.

It's the exact same reason old cartridge games lose their ability to save and computers and consoles forget what the time is. A small battery provides just enough charge for a few years to retain some data in a memory module, a bit like a digital watch.

The batteries are actually slightly recharged, a bit like you used to be able to turn a GameBoy on and off again a few times with the contrast set higher and higher so you could actually see what you were playing. But that charge will dissipate the longer the battery is disconnected from the voltage source, resulting in the total loss of data.

I had a problem with a Super Metroid cart and thought that it might be the battery. I bought a gamebit screwdriver and a new battery to fix it but before I replaced the battery I just tightened the screws on the cartridge to see if that worked and it did.May be worth trying that first.
